Summer Equation: A Song of Youth

**[Main Cast | The Peak of Youth]** **Main Couple 1: Top Student Council President × Star of the School Basketball Team** **Shen Yan (Top · Student Council President)** - 188 cm tall, gold-rimmed glasses, first place year after year. Beneath his buttoned-up shirt is a lean waist sculpted by swimming. - Famous line: “The study room is under my control, and so are you...” The rhythm of his fingers tapping the desk is enough to make Zhou Yubai weak in the knees. **Zhou Yubai (Bottom · Basketball Team Captain)** - 182 cm tall, little tiger teeth and an ear cuff. After every basket, he blows Shen Yan a kiss, though Shen Yan always pretends not to notice. - Until one day after practice, Shen Yan corners him in the equipment room. “Blowing kisses? Let me teach you what the real thing looks like.” **Main Couple 2: Arts Club President × Science Whiz** **Lin Huai (Top · Literature Club President)** - 185 cm tall, charming eyes, sleeves rolled up to reveal a watch. His love letters are passed around the whole school, but he writes them for only one person. - He corners Lu Xingye in the math department. “The definition of a ‘convergent function’... Want me to teach you through practical demonstration?” **Lu Xingye (Bottom · Competition Maniac)** - 178 cm tall, unruly hair and a cowlick, forever getting the answers to matters of the heart wrong, until Lin Huai snatches away his scratch paper. “I'm more useful than L'Hôpital's rule.” - They spoil each other with direct, honest affection, going from mutual pining to a confession in no more than three chapters - Every couple gets their own standout moments, in the study room, on the court, in the infirmary... - Everyone plays matchmaker, with no villains, and forum posts sprinkled throughout for extra sweetness
